What Colour eggs do Australorp chickens lay?

Australorps are a popular breed of chicken known for their friendly temperament and high egg production. One of the most frequently asked questions about Australorps is what color eggs they lay. In this comprehensive article, we will provide a detailed overview of Australorp egg color and appearance.


Australorps lay light brown eggs with a slight pink tint. Their eggs tend to be medium to large in size. The egg color results from pigments deposited as the egg develops in the oviduct. While most Australorps lay light brown eggs, some strains may produce white or tinted eggs.

What is the typical egg color of an Australorp chicken?

The typical egg color of an Australorp chicken is light brown with a slight pinkish tint. The light brown coloration comes from pigments that are deposited on the eggshell as it develops within the hen’s oviduct. Here are some more details on standard Australorp egg color:

  • Base color is light brown
  • Pinkish or rosy tint
  • Faded brown spots may be present
  • Appearance is similar to eggs from Rhode Island Reds

While most Australorps lay eggs matching this description, there can be some variability between individual hens. The exact shade can range from a very pale brown to a darker tan color. However, a light brown base with a hint of pink is considered typical.

What causes the light brown egg color?

The light brown eggshell color of Australorps is caused by pigments that are deposited on the egg as it travels through the oviduct prior to laying. All eggs start out white inside the hen. As the egg moves down the oviduct, pigments are added from glandular secretions.

The main pigments responsible for brown egg color are:

  • Protoporphyrin – Produces base brown color
  • Biliverdin – Causes blue-green eggshell tinting

In Australorps, protoporphyrin produces the light brown base color. Biliverdin contributes a pinkish-red tint. The combination of these two pigments results in the typical light brown eggs with a rosy hue.

Do all Australorp chickens lay light brown eggs?

While light brown is considered the breed standard, not all Australorp individuals will lay eggs of this color. Here is some information on variations:

  • Most Australorps will lay eggs close to the breed description of light brown with a pink tint.
  • Some strains have been bred to lay white or tinted eggs.
  • Very rarely, an individual hen may naturally produce darker brown eggs.
  • Diet, environment, and genetics influence egg color.

So while light brown is the norm, Australorps have the ability to lay eggs in a range of light brown shades. Purebred birds from show lines are most likely to lay standard light brown eggs. Backyard flocks may show more variability.

How does Australorp egg color compare to other chicken breeds?

Australorp eggs are similar in color to other brown egg laying breeds like:

  • Rhode Island Reds
  • Plymouth Rocks
  • Orpingtons
  • Sussex
  • Jersey Giants

However, Australorp eggs tend to be a lighter brown than these breeds. The pinkish tint is also unique to Australorps. White egg layers like Leghorns produce eggs that are chalky white. Dark brown eggs come from breeds like Marans and Welsummers.

Here is a table comparing the egg colors of different chicken breeds:

Breed Egg color
Australorp Light brown with pink tint
Orpington Medium to dark brown
Plymouth Rock Light to medium brown
Rhode Island Red Light to medium brown
Leghorn White or very pale cream
Marans Very dark chocolate brown

Do Australorps lay pink or blue eggs?

Australorps do not naturally lay pink or blue eggs. However, some strains have been bred specifically for these unique egg colors:

  • Pink egg layers – Through breeding, some lines produce a darker pink egg rather than the typical light brown.
  • Blue egg layers – Rare strains have been developed that lay blue-tinted eggs.

These specialty strains are not the norm for the breed. Purebred Australorp chickens from standard breeding lines will always lay light brown eggs, not pink or blue.

What affects Australorp egg color?

While genetics play the biggest role in determining egg color, other factors can cause subtle variations in shade. Here are some things that influence the color of Australorp eggs:

  • Genetics – The hen’s genetic makeup controls color. Purebreds lay standard light brown eggs.
  • Diet – Diet impacts pigment levels. For example, more yellow-orange plant pigments can lead to darker yolks.
  • Stress – Stress reduces pigment deposition, potentially resulting in lighter colored eggs.
  • Age – Younger pullets tend to lay lighter colored eggs as pigment levels increase with maturity.
  • Environment – Extreme heat can bleach eggs, resulting in paler color.

While these factors cause subtle variation, the overall egg color remains in the light brown spectrum.

How large are Australorp chicken eggs?

Australorps are considered a good laying breed and produce medium to large sized eggs. Here are some typical details on Australorp egg sizes:

  • Minimum weight of 53 g / 1.9 oz
  • Average weight around 60 g / 2.1 oz
  • Can reach 70+ g for very large eggs
  • Oval shaped with a rounded end
  • Light brown color
  • Smooth, hard shells

As a utility breed developed for egg production, Australorps lay generously sized eggs. The large eggs were favored by early farmers and settlers in Australia.

How many eggs does an Australorp chicken lay?

Australorps are very productive layers. On average, they produce around:

  • 250 eggs per year
  • 4-5 eggs per week

This level of high production helped establish their popularity as a farmyard breed. With their large brown eggs, an Australorp hen can supply a family with plenty of eggs for cooking and baking.

At what age do Australorps start laying eggs?

Australorps typically begin laying eggs at around:

  • 5-6 months of age

Known for their stellar egg laying, Australorps are early starters. If hatched in spring, they will often begin producing eggs by late summer or early fall.

Does egg color affect taste?

Egg shell color does not affect the taste, quality or nutritional content of the egg itself. Differences in color are limited to the outer shell. The interior quality remains the same across breeds and egg colors. Some key points:

  • Shell color does not impact flavor
  • Interior egg components like the white, yolk, and nutrients are the same
  • The only difference is the outer shell pigmentation

So while Australorp eggs may be a different color from other breeds, the contents and taste are unchanged. The eggs are just as delicious and nutritious as standard white chicken eggs.

Why choose Australorp chickens?

Australorps are a popular backyard and homestead chicken breed for many reasons. Here are some of the benefits of keeping Australorps:

  • Excellent layers of 250+ light brown eggs per year
  • Calm, friendly personality good for families
  • Low noise levels due to minimal clucking/crowing
  • Tolerant of a wide range of climates and conditions
  • Medium sized dual purpose breed provides meat as well
  • Hardy and low maintenance once established

With their high production of large light brown eggs, Australorps are a top choice for many egg farmers and homesteaders. Their placid temperament also makes them suitable as pets.


In summary, Australorps are a heritage chicken breed best known for their prodigious output of light brown eggs with a pinkish tint. Their medium-large eggs can reach 60 g in weight and around 250 per year per hen. While individual variations can occur, light brown shells with a rosy hue are considered typical for the breed. Along with their stellar laying abilities, Australorps have a calm personality that suits them well to family flocks. Their beautiful brown eggs and friendly nature help explain their enduring popularity over the years.

So in answer to the original question “What colour eggs do Australorp chickens lay?”, the standard color is a light brown with a subtle pinkish hue – very unique and charming! With their high production and great temperament, Australorps make an excellent addition to any backyard or small farm. Their gorgeous brown eggs are both beautiful and bountiful.
